GEORGE COOK, OF LOUISVILLE, KENTUCKY.

PAPER-HANGING MACHINE Application filed March 26, 1908.

To all whom it may concern:

Be it known that 1, GEORGE Cook, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful improvements in Paper-Hanging Machines; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to machines for hanging paper, and has for itsobject to provide a machine which will automatically unroll and trim thepaper and paste it on the wall without the necessity of touching thepaper with the hands.

Another object is to provide a machine of this kind which may be rolledalong the wall or ceiling after the manner of a carpet sweeper, andwhich w ill at the same time automatically unwind paper from a roll,cover it with paste and place it upon the wall in correct position.

Another object is to provide in a machine of this kind convenient meansfor transversely cutting off the paper, and means for trimming thepaper.

Still another object is to provide in a machine of this kind suitablemeans for carrying paste which will permit the machine to be used eitheron the ceiling or side wall without changing any of its adjustments.

For these and other objects which hereinafter appear my inventionconsists of certain novel arrangements and combinations of parts ofwhich the herein described paper hanging machine is an embodiment.

While herein I describe minute details of my invention I do not limitmyself to these as the same may be greatly varied Without departing fromthe spirit and scope of the invention.

In the annexed drawings forming a part of this specification, and inwhich like reference characters designate like parts throughout theseveral views, Figure 1 is a side elevation of my device as applied tothe ceiling of a room, Fig. 2 is a longitudinal vertical sectional viewtaken on the line 22 of Fig. 3, Fig. 3 is a top plan view partly insection, Fig. I is a transverse sectional view taken on the line 44: ofFig. 2, Fig. 5 is a transverse sectional view taken on the line 55 ofFig. 2 looking in the direction of the arrows,

Specification of Letters Patent.

Patented May 4:, 1909.

Serial No. 423,464.

Fig. 6 is a transverse sectional view in detail taken on the line 55 ofFig. 2 looking in the direction opposite to the arrows, and Fig. 7 is anelevation of the compressible roller.

Referring more particularly to the drawings, the numeral 1 indicates theside pieces of the machine frame. Axles 3 extend transversely throughthe side pieces near the upper edges thereof and are provided at theirends with rubber-tired wheels 4 which are adapted to travel over thesurface to be papered. A compression roller 5 is j ournaled between theside pieces preferably beneath one of the axles 3. This roller consistsof an elongated cylinder 6 having a central longitudinal square bar toreceive a square axle or shaft 1 1-, the ends of which extend throughthe side pieces of the machine frame and are held in place by acotter-pin 16 extending through one end of the said shaft and a shoulder17 formed at the other end of the shaft. The outer surface of thecylinder is provided with longitudinally extending outwardly curved leafsprings S, which are attached at their upper ends to the cylinder byscrews 9.

To remove the cylinder 6 from the machine, the key 16 is removed and theshaft 14 withdrawn from the cylinder. The cylinder, thus removed, may beinserted through the center of a roll of wall paper, the expansivetendency or force of the springs S holding the roll of paper firmly inplace. The cylinder may be then replaced in position, and, if desired, awasher 20 may be interposed between the key 16 and the adjacent sidepiece of the frame. Longitudinal extensions 21 are formed at the upperrear corners of the side pieces between. the ends of which is rotatablymounted a pressing roller 22, the axle of which is slidably mounted inslots 23 and the ends of said axle are normally held at the inner endsof the slots by push springs 2 1 whereby the roller 22 is caused tofirmly bear against the ceiling or other surface to be paper-ed.

A roller 25 is mounted beneath the roller 3 at the front end of themachine, the ends of the roller axle being j ournaled in supports 26arranged at the ends of the paste vessel 27, said supports also servingas hangers for the paste vessel whereby the latter is permitted to swingin either direction with the roller axle as a center. Rotatably mountedwithin the paste vessel is a paste brush roller 29 the bristles of whichare adapted to dip into the paste contained in said vessel.

In practice, as the roll 19 unwinds, the paper 30 passes between therollers 25 and 29 and then rearwardly over the roller 22,

the paper in passing between the rollers 25 and 29 rotating the latterand causing it to spread the paste in the receptacle 29 on the paper. Ifdesired, belts or sprocket chains 31 and 32 may connect the rollers 5and 25 This I accomplish by the following mechanism. At convenientpoints of the side pieces 1 near the roller 25, I provide transverseopenings 37 and 38 to the side walls of which are rigidly secured, as bymeans of screws 41,

the lower stationary transverse blade 42 having the upper cutting edge43 adapted to cooperate with the cutting edge 44 of an upper movabletransverse blade 45, pivoted to the projecting end 46 of the blade 42 asclearly shown in Fig. 5 of the drawings.

The free end of the movable blade 45 proj ects through the opening 38and is provided with a handle 47. This blade is normally held above orin spaced relation with the stationary cutting blade by a spring 49 andmay be actuated in one direction against the tension of said spring byan operating cord 50 attached to the handle end thereof. Between thecutting blades 42 and 45 and the roller 5, in parallel relation with oneof the side pieces 1, is mounted by means of thumb screws 51 and 52, alower stationary trimming blade 53, the thumb screws passing throughthreaded bushings 54, and having screwed on their inner ends jam nuts 55and 56, respectively, between which the blade 53 is mounted. ming blade53 may be adjusted laterally or transversely to trim the wall paper at agreater or less distance from one edge.

Pivotally mounted upon the thumb screw 51 is an upper pivoted trimmingblade 57 provided at its pivoted end with an outwardly curved portion 58to receive one edge of the paper 30 and to permit it to pass between thetrimming blades (see Fig. 6). A coil spring 59 is arranged between thefree end of the movable trimming blade and one of the side pieces 1 tohold said blade nor- 60 mally in spaced relation with the stationarytrimming blade. The free end of the pivoted trimming blade is alsoprovided with a laterally projecting finger 60 which extends through anopening in the adjacent side 65 piece 1, an operating cord 71 beingattached By this arrangement the trim' to said finger whereby thepivoted trimming blade may be moved in one direction against the tensionof the spring 59.

I will now describe an automatic arrangement for operating the pivotedtrimming blade which may be detached whenever it is desired to o eratesaid blade by the cord 71. An upward y projecting ear 72 is formed atthe free end of the pivoted trimming blade 57. A stub shaft 7 4 ismounted in a bushing 75 in the adjacent side piece above said blade, theinner end of said shaft being of square form, as indicated at 76 and theouter end thereof provided with a sprocket wheel or pulley 77 adapted toreceive the band 32 whereby the shaft 74 is caused to rotate upon movingthe machine over a surface.

A cam 78 is arranged near the inner end of said stub shaft and isreceived by an eccentric strap 79 at one end of a link 80 pivoted to theprojecting ear 72 of the movable trimming blade. By this construction,it will be evident that, upon imparting movement to the shaft 74, theeccentric 78 will alternately raise and lower the eccentric straps 79and thus operate the pivoted trimming blade.

Cross pieces 81 extend between the side pieces in order to more securelybrace the latter. A handle 82 having a fork 83 to receive projections 84extending from the side pieces of the machine frame is shown as a meansfor properly handling the machine.

In practice, the roll 19 having been sufficiently unwound to cause aportion of the paper 30 to pass between the rollers 25 and 29,respectively, and over the roller 22, the machine is moved in adirection away from the roller 22. The rollers 4 in passing over theceiling or other surface to be papered cause the rollers 5 and 25 tounroll the paper and the eccentric 78 to operate the pivoted trimmingblade. The machine is thus moved until the desired amount of paper hasbeen unrolled as far as the cutting blades 42 and 45. The blade 45 isthen actuated by pulling upon the cord 50 to out the paper 30. Themachine is then passed still farther over the surface to be papereduntil all the paper out off by the pivoted cutting blade 45 has beenapplied to the wall by the roller 22.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without re quiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention.
